' FIREPLACE.

Application led September 16, 1926. Serial No. 135,886.

This invention relates to fire places, more particularly to an air circulating and heat- -ing attachment for positioning within the'V fire place, that is to say an open fire place or grate, and the invention has for its object to provide, in a manner as hereinafter set forth, a heating attachment for facilitating the circulation of air around and discharg ing the same in a heated condition into the room with which the fireplace is associated thereby increasing the temperature of the room, and further for .utilizing the heat atthe sides,^back and top of the fire place for heating such air during the circulation thereof through the attachment, whereby when the air is discharged into the room it will be in a heated condition, and materially increase the temperature of the. room with respect to the temperature created by ran open grate tire when the attachment is not employed, and with the attachment set up that the heat derived from the open grate fire will also be employed for heating the room' in connection lwith the heated air which circulates around the fire place land discharged into the room.V

It is'an accepted custom, in connection with open fro-nt fire places, to place tire bricks at the side and back walls of the fire place, and such arrangement is had because the heat at such points is so great that ordinary brick and stone will not stand it very long, and under such conditions it is is not employed for heating the room, with which the tire place is associated, and an at tachment in accordance with this invention, is so set up as to trap this waste heat and utilize it for heating air circulated around the ire place and discharging such air into the room with which the fire place is associated or into other rooms. The air enters at the bottom of the sides of the attachment, passes throughout the sides, as well as the backofthe attachment, and also through 'the top of the attachment and discharges into the room and by this arrangement the sides,

back and top ofthe attachment are heated under such conditions heating the air tol a material extent so that the temperature of the room will be increased over that which it would be if the iire alone from the grate was employed for heating the room.

A further object of the invention is to provide, in a manner as hereinafter set forth, a heating attachment for the purpose referred toso constructed and arranged as not to impair the passage of the products of combustion from the fire place through the iiue o-r chimney.

Further objects of the inventiony are to provide, 1n a manner as hereinafter set forth, a heating attachment for the purpose referred to which is simple in its construction and arrangement, strong, durable, com- Jact', thoroughly efiicient in its use, readily installed with respect to a fire place and comparatively inexpensive to set up.

iVith the foregoing' and other objects in View, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described, an'd illustrated in the accompanying` drawings' wherein is shown an embodiment of theinvention, but it is to be understoodv that changes, variations and modifications can be resorted to which fallwithin the scope of the claims hereunto appended.

A heating attachment in accordance with this invention, can be readily installed in anopen ire place already built. It also can be installed during the building of chimneys on fire places and provision can be made fer any size opening', as well as for admitting cold air in behind the fire place, in the side ofthe chimney itself, inside a room, or from the outside.V The attachment can be set up 'of any suitable material and as before sta-ted can be built simultaneously with the building of theftire place and chimney, or it can be lan independent device and positioned within the fire place after the same'has been built. One embodiment of the invention is illustrated in the drawings, and referring to these latter the heating attachment comprises aninner section l, an outer section 2, a top section 3, and a front section 4. The upper ends of the sections l and 2 incline downwardly from the front to the rear there-y groove provided by the rabbet 10.

. part of. The sec-tions 1 and 2 are substantially U-shape in plan. The section 41 is of inverted U-shape. The top section 3 inclines downwardly fromfront to rear. f

The front section 11 is of inverted U-shape, and has each side thereof indicated at G and its top at 7. The sides (3 of the section fi are of greater thickness than the upper portion 7 of the top 7. Secured to the inner face of the thin part 7 of the top 7, and flush with the top and side edges of the section 1 is a bar 8. rihe holdfast devices for securing said bar in position are indicated at 9. The bar 8 has thelower portion of Vits forward face rabbeted, as at v10, which in connection with the thin part 7 of the top 7 forms a guide groove. The lower part of the top 7 is indicated at 11, and constitutes what may be termed a cross piece for connecting the sides 6 of the section l together. The cross piece 11 has its upper face formed with a lengthwise extending guide groove 12, arranged in alinement with the guide The side marginal portions 7 of the top 7 below the thin upper part 7, but above the cross piece 11, are' of greater thickness than that part 7', of the top 7, which is positioned between the side marginal portions 7 andV below the thin upper part 7 The thickened side marginal portions do not extend to the upper edge of the top 7, and have the bar 8 mounted thereon. The 7', of the top 7 is formed with a series of spaced vertically disposed substantially oval shaped hot air outlet openings 13 and associated with these latter is a slotted con* trolling` side 14, operating in the guide The slide 14- is formed with a forwardly extending knob or finger piece 15. The part 7 of the top 7, is formed centrally with a lengthwise disposed slot 16 and through which extenos the shank of the finger piece or knob 15.

The rear face of the section 4 at each side thereof, isformed with a vertically disposed groove 17, which extends from a point in proximity to the lower end of each side 6 to the top edge or upper face of the cross piece 11. The side walls of the groove 17 are inout as at 18. The outer side wall of the groove 17 is extended to the upper edge of each thickened side marginal portion 7 of the top 7. Arranged within each of the grooves 17, as well as being retained therein by the inout side walls thereof, is a vertically movable slide 19, employed for controlling the supply of cold air to the attachment, through a vertically disposed rectan-Y gular opening 2O at the lower portion of each side 6 of the section 4. The slide 19 is provided with a knob or finger piece 21 which projects forwardly through an opening 20.

The forward edges of the outer section 2,

abuts against the sides 6 ofthe front section Y 4: and are secured therewith by the hold fast Adevices 22. The forward edges of the inner section 1 abuts againstthe rear of the sides 6 of the section L1 and are secured therewith bythe hold fast devices 23.

The sectiony 1 is provided with an vopen top, open bottom and open front and comprises a. back wall 24 and a pair of sidey walls 25, 26, see Figure 6. The section 2 is formed with a back wall 27, and a pair of side walls 2S, 29. rEhe top edge of the back wall 27 of the section 2 rabbeted as at to provide a seat. The top edge of the side walls 28 and 29 of the section 2 is provided throughout with a lengthwise extending groove which is coextensive with said edge. The top edge of the wall 2d of the section 1 is rabbeted as at 35 to provide a seat and which is coextensive with said edge. rlhe top edge of each side wall of the section 1 is provided with a groove 36 which is coextensive with said edge.

The top section@ of the attachment is removably mounted vin the seats and grooves formed in the top edges of the sections 1 and 2, and as the sections 1 and 2 incline downwardly from front to rear the top section 3 will be disposed in the same inclination. The outer section 2 of the attachment is of greater height than the inner section l, see lligure et. Thetop section 3 consists of a 'hollow apertured body with its top pro- 4 jecting beyond its bottom and with the sides and rear of the top thereof formed with a depending 'flange 37 seating in the top edges of the section 2. The top of the section 3,Y

which is indicated at 5S has its forward edge abut against the bar 8see Figure t. The bottom of the section 3, and which is indicated at 39, seats in the top edges of the walls of the section 1 vand further extends in close proximity to the slide 11i, see Fig. e..

vides a combined air circulating and heatingchamber of an area to extend throughout the sides, back and top of the attachment and said chamber is indicated at 42. The openings 2O provide cold air inlets to the chamber 42 and the openings 13 provide hot air outlets for the chamber 42. The section 1 forms a lire box d3 and is provided with means as at 141, 45 for supporting a grate 416 therein it' desired. The outlets 11 are of flaring contour and extend from front to rear with respect to the top of the section 3, or rather with respect tothe top of the at- Cil ifi() lili) Ll l) tachment. The wall of each of the outlets 41 is rounded as at 47 at the top and bottom thereof.

The chamber 42 is so shaped, as to provide a pair kof side portions 48, 49, yav back portion 50 and a top portion 51 into which open the side portions 48, 49 and back portion 50 and in this connection see Figure 5.

53 are of less width than the width of the portion 50 of the chamber 42. The deflectors 52 and 53 provide means for directing the inlet air upwardly towards the top portion 51 of the chamber 42. The air as it` travels upwardly will be heated before it enters said portion 51 at the rear thereof, and the air will then travel around t-he conduits 40 and be discharged through the outlets 13. The deflectors also provide means to increase the radiating capacities of the side and back walls of the inner section.

The outer side and back wall of the chamber 42 can be formed by the side and back walls of the opening in which the attachment is placed and with the section 3, supported upon the top of the section l and abutting against the aforesaid walls. Further it is to be understood that sections 1, 2 and 3 can be cast integral with each other.

The attachment provides means for utilizing the heat at the sides, top and back of the fire box 43, for heating the air travelling through the chamber 42. The air enters the chamber 42 through the openings 2O and is discharged therefrom in a heated condition through the outlet 13 into the room with which the fire place and heating attachment` is associated, or into other rooms, and under such conditions materially increasing the temperature of the room, -with respect to that temperature which would be given to the room by the heat alone from a fire box, and therefore it is thought that the many advantages of a heating attachment, in accordance with this invention can be readily understood, and although the preferred embodiment of the invention is as illustrated and described, yet it isv to be understood that changes in the details of construction can be had which will fall within the scope of the invention as claimed.
